Application tiled June 25, 1884. Serial No. 135,978. (No model.) Patented in France February 1, 1882, No. 147,163; in Germany February 11, 1882, No. 20,302; in Belgium March 3l, 1884, No. 64,688; in England April 2, 1884, No. 5,837; in Italy April 12, 1884, No. 16,714; in Russia April l2, 1884; in Spain July 30, 1884, No. 6,168, and In Austria September 12, 1884, Nu.21,527.

To all whom it may concern:

Be it known that I, HENRY FERDINAND SAINI` REQUIER, a citizen of the Republic of France, and residing in Asnires, France, have invented certain Improvement-sin Machines for the Reduction ot'Grain, (for which I have obtained a certitcate of addition dated March 24, 1884, to French Patent No. 147,163, dated February 1, 1882; a Belgian Patent No. 64,688, dated March 31, 1884; a British Patent No, 5,837, dated April 2,1884; an Italian Iatent No. 16,714, dated April 12, 1884; an Austrian Patent, No. 21,527, dated September 12, 1884; a German Patent, No. 20,302, February 11, 1882; a Spanish Patent, No. 6,168, dated July 30, 1884, and for which I applied for Russian Patent April 12, 1884,) ot' which the following is a specification.

My invention consists of certain improvements in thegrain-reducing machine for which Letters Patent ofthe United States No. 277, 79() were granted to Ine May 15, 1883, the present improvement relating more especially to the construction and mounting of the cuttingknives, securing the horizontal table or disk to the vertical spindle or shaft,and providing the said table or disk with an annular cover to revolve therewith, as fully described and claimed hereinafter.

In the accompanying drawings, Figure l is avertical section of my improved machine. Fig. 2 is a plan view, partly in section, showing the rotary table, its cover, and the knifering. Fig. 3 is a sectional view, drawn to a larger scale, of a portion of the rotary table. Fig. 4 represents views of cutting-knives detached, drawn to a smaller scale than Fig. 3. Fig. 5 represents similar views of intermediate washers, also detached. Fig. 6 is a vertical seetion,drawn to a larger scale,of a portion of the knife-ring. and Fig. 7 is a corresponding plan view of a portion of the knifering and sets of knives.

N is the cylindrical casing or frame with the usual discharge passages, M, forming part thereof, and to the top of this casing is bolted the cover N', with central conical portion, G, to the upper'end of which is adapted the adjustable feed-spout D. IVithin the cone G is another cone, F, leaving an annular passage between the two for the supply of grain to the rotary table or disk. III the present instance I employ only one horizontal table or disk, I, instead of t\vo,as in my former apparatus, and this disk is secured to the vertical driving-shaft or spindle through the medium of a sleeve, (c. The upper end of the spindle A is made conical, and on this is iirmly tted the conical portion ofthesleeve a, whose lower cylindrical portion is adapted to bearings in 6o an oil-box, E, carried by the casing. The centra-l opening in the hub of the disk I is made conical to tit over the outer conical surface of the sleeve a, and is firmly secured thereon by suitable nuts and washers adapted to the screwed end of the spindle A. This spindle is adapted at its lower end to the usual stepped bearing. H, and is provided with the drivingpulley B.

The upper surface of the table or disk I, 7o onto which the grain falls, is provided with radial grooves, as described in my former patent; but instead ot' relying on the cover of the casing to retain the tlyiug grain within the grooves I employ an annular cover, K, which is secured to the upper surface of the disk and therefore revolves with the latter, leaving passages for the grain along the grooves in the face of the said disk, as shown in Fig. 3. The inner rim of this annular cover is turned to up or flared, so as to prevent the grain from escaping out over the top of the cover.

The sets of cutting-knives are in this case carried by a ring, .Lwhich is clamped between the upper tlanged rim of the cylindrical casing N and the cover N. The knivesj are ar ranged in tangential sets, as described in my former patent, and in this case are secured to the ring J by horizontal bolts and nutsf, spaciI'Ig-washers j', Fig. 5, being alternated 90 with the knives. The latter project below the ring, as shown in Fig. 6, and the knives of each set are secured together at their lower ends with intermediate washers by means of bolts and nuts. rlhe portions of the knives between the washers at top and bottom form the cutting portiouswith free spaces between for the passage of the cut grain. The upper and lower ends of the knives are enlarged, as shown in Fig. 4, to give a large enough sur- IOO face for the formation of the holes for the bolts.

The operation of the machine described is substantially the same as that of my patented anparatus before referred to and will not need further explanation.

l claim as my invention* l. The combination ofthe casing of a grainreducing machine having a bearing-box, E, With a horizontal disk, and a Vertical driving-spindle, A, carrying a sleeve adapted to said bearingbox and havingr a conical portion on which the hub of the said disk is secured, substantially as set forth.

2. The combination of the casing, the feedspout,and a ring carrying cutting-knives, with a rotary grooved table inline with saidknives 332,006 Y ai forth.

In testimony whereof I have signed my name to this specication in the presence of two subscribing Witnesses.
